THE SIGNAL THAT RULES US: Wi-Fi, 5G, satellites, and the unseen empire of connectivity (The Code of Everything, Band 17) - Softcover

Inhaltsangabe

What does your phone actually ride on when you stream, text, or tap to pay? The Signal That Rules Us pulls back the curtain on the invisible empire of Wi‑Fi, 5G and satellites, showing how radio waves are generated, routed and regulated — and why they sometimes drop, slow or disappear. Clear, spare explanations and sharp metaphors turn electromagnetic theory into practical sense: think of bands as lanes, routers as toll booths, and satellites as long, slow conveyor belts across the sky.

You’ll learn how home networks and cell towers really work, how to read coverage maps, basic troubleshooting that actually fixes things, what 5G can and cannot do, and why policy and economics decide who gets fast, reliable access. Classroom‑friendly, slightly witty, and full of useful takeaways, this book arms curious teens and adults with the knowledge to diagnose problems, demand better service, and understand the stakes of the connected world.
